HM/E01 Plug-On Transmitter
15 September 2017
Digital Hybrid Wireless
®
U.S. Patent 7,225,135

LECTROSONICS, INC.2
The HM Digital Hybrid® UHF plug-on transmitter features a DSP-based design that allows the transmitter to operate in its native Digital Hybrid Wire­less
®
mode, Lectrosonics 200 Series, 100 Series, IFB product groups, plus three modes for compatibility with analog receivers from other manufacturers. A unique multi-voltage phantom power feature allows the transmitter to be used with virtually any microphone, including high-current condenser types, expanding its usefulness in high-end applications such as motion picture production.
The transmitter provides up to 1024 frequencies selected with the membrane switch keypad. The input amplifier uses an ultra low noise op-amp for quiet operation. It is gain controlled with a wide range dual envelope limiter, provid­ing over 30 dB of headroom above full modulation. A 24-bit A-D converter digitizes the audio, then filters supersonic noise above 21 kHz. The resulting signal is encoded with a proprietary algorithm to produce an analog data sig­nal for RF transmission. The underlying RF link is an optimized FM system with +/-75 kHz wide deviation for a high signal to noise ratio.
The antenna is formed between the lower housing of the transmitter and the attached system. It functions as a dipole radiator when attached to a hand­held microphone and somewhat like a ground plane antenna when con­nected into a mixer. The conical shaped collar on the input coupler is made of DuPont
TM
Delrin® to improve the ERP of the antenna in the uppermost
frequency blocks.

The HM transmitter is powered by two AA batteries. We recommend using lithium batteries for longest life. Lithium batteries provide approximately 9 hours of operation at room temperature, without phantom power enabled.
The battery status circuitry is designed for the voltage drop over the life of lithium batteries.
To install new batteries:
1) Slide the battery compartment door outward and swing it open.
2) Insert the new batteries into the housing. One battery goes in positive (+) end first, the other negative (–) end first. Look into the battery compart- ment to determine which end goes in which side. The side with the plastic ring and smaller round opening is the side which must contact the (+) posi­tive end of the battery. The other battery is inserted in the opposite polarity.
Note: It is possible to install the batteries backward and close the battery door, but the batteries will not make contact and the unit will not work.
3) Close the Battery Cover and slide it inward until it snaps shut.

Set Up in 100 kHz Mode
The Frequency Screen displays the operating frequency in MHz or as a two-digit hexadecimal number that corresponds to the equivalent Lectrosonics Frequency Switch Setting. The example of the two-digit display shown here indicates CH (channel) and 2C as the frequen­cy. Repeatedly pressing the FREQ button toggles between the two displays. Press and hold the FREQ button and use the Up and
Down arrows to select the frequency.
Set Up in 25kHz Mode
The hexidecimal display in the 25 kHz mode will appear with a decimal suffix to indicate the 25 kHz steps.

number
Frequency displayed
in MHz
The operating frequency of the HM is displayed either in MHz or as a two-digit hexadecimal number. Pressing the FREQ button toggles between the two display modes. The frequency can be set with the unit in Standby Mode or while powered up for normal operation.
Note: You must first find a clear frequency with the receiver, then set the transmitter to match.
To change the Operating Frequency of the HM
transmitter:
1) Press the FREQ button to enter this screen.
2) While holding the FREQ button, use the UP or DOWN arrow buttons to move the operating frequency up or down in 100 kHz increments from the current setting. Holding the UP or DOWN arrows will cause rapid scrolling through the frequencies.
Note: The operating frequency displayed on the LCD wraps as it reaches the upper or lower end of its range.

Attaching a Microphone and Adjusting the Gain
TO AT TACH
TO REMOVE
Hold the transmitter case with the microphone pointed upward. Rotate the collar in the direction shown.
Pull on mic to ensure it is locked.
Press firmly, listen for click. Depress collar fully.
Click!
To attach the mic, insert the HM into the XLR connector. Press the connector into the microphone until the tapered collar retracts and listen for a “click” that indicates the connector has locked onto the microphone. Gently pull on the mic to ensure proper locking
has occurred.
When removing the microphone from the HM, hold the transmitter in one hand and twist the collar with the other hand until the microphone disengages. Do not pull on the microphone as it may prevent the connector from releasing.
The front panel Modulation LEDs indicate limiter activity. (See chart below.) Once set, the transmit-
ter’s audio level setting should not be used to control the volume of your sound system or recorder levels. This gain adjust­ment matches the transmitter gain with the microphone’s output level, the user’s voice level and the microphone’s position. The audio input level can be set with the unit in Standby Mode or powered up for normal operation.
Signal Level -20 LED -10 LED
Less than -20 dB
Off Off
-20 dB to -10 dB
Green Off
-10 dB to +0 dB
Green Green
+0 dB to +10 dB
Red Green
Greater than +10 dB
Red Red
Different voices will usually require different gain settings, so check this adjustment for each person using the system. If several different people will be using the transmit­ter, set it for the loudest voice.
1) Set the required phantom power mode before attaching the microphone.
2) Briefly press the AUDIO and FREQ buttons at the same time, then press and hold the AUDIO button to enter the setup screen.
3) Use the microphone in the manner in which it will be actually used.
4) Observe the HM audio level LEDs while speaking or singing into the micro­phone at the same voice level that will be used during the program. While holding the AUDIO button, press the UP or DOWN arrow buttons until the both the -20 and -10 LEDs glow green, with the -20 LED occasionally flick­ering red (+0 dB to +10 dB range during peaks).
Note: Setting the audio level too high reduces the dynamic range of the audio signal. Setting the audio level too low may cause hiss and noise in the audio.

Using the Polarity-Reversing Barrel Adapter with Measurement Microphones
A polarity adapter may be needed if you experience noise, low output or distortion with meaasurement micro­phones such as Earthworks M30 or Rode NTG3.
Insert the barrel adapter provided with the HM transmitter between the micro­phone and transmitter as shown.
NOTE: This adapter is included with the TM400 test and measurement system, but is available as a separate item with the HM transmitter and other wireless equipment.
Important: The only way to unlock a locked transmitter is to remove the battery. It cannot be unlocked or powered off using the buttons. The unit will always power up in “unlocked” mode.

The Lock mode protects the transmitter from accidental changes to its settings.
1) Ensure the HM setup is complete.
2) Simultaneously press both the UP and DOWN arrow buttons to start the Lock timer. When the timer reaches zero, “Loc” is displayed and the controls are locked.
